A hand held masking machine for applying tape along both edges of a sheet of masking material which has relatively movable frame portions that engage and journal opposite ends of a roll of masking material to accurately position tape being applied to its edges; frame portions adapted to have end portions of tape on the machine adhered thereto so that the masking machine can adhere tape along both or only a desired one of the masking material edges; an adjustable cutting blade assembly that accommodates applying tapes of different widths to the masking material, and specially longitudinally folded rolls of masking material so that the taped masking material may be wider that the roll from which the masking material is dispensed.
